β-CDp (β-Cyclodextrin Polymer) is fabricated from polymerization of β-cyclodextrin and a highly hyperbranched, three-dimensional network was formed. The β-CDp network creates thousands of anchor points in all directions, keeping the electrode intact even as particles swell and shrink. One of the most remarkable features of β-CDp binders is their ability to "self-heal" during battery operation. The hydrogen bonds and host-guest interactions within the network are dynamic. If a bond breaks due to silicon expansion, the abundant functional groups allow it to re-form and "click" back into place elsewhere in the network. This ensures that even if a silicon particle cracks, it remains electrically connected to the rest of the electrode rather than becoming "dead weight."
